"You will need to capture the video using the phones camera. The phone has built in video coders (implemented using HW) that can can compress the video signal quickly enough to send over the 3G link. The overall system you need is to either OPTION 1…"

Interested in UAVs but want unconventional setup
Started this discussion. Last reply by Bill Bonney Dec 1, 2012. 37 Replies 0 Likes
Hey guys, I found out about the UAV scene and want to get involved, and was hoping that everyone could answer some questions. My queries are as follows:(1) Is using a Wi-Fi signal and on-plane access…Continue

McCarthy Wynkoop replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"That's what I was talking about."
Bill Bonney replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"That's cheap at just shy of $4000 :-o. I'm pretty sure that it's exceeding permissible power levels for civilian use. Even with a Radio Am license you are probably restricted to 1W (30dB), and less in some countries depending on…"
Bill Bonney replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"there is this http://store.diydrones.com/PhoneDrone_Board_p/br-phonedrone.htm but i don't know anything about it other what I just read."
McCarthy Wynkoop replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"Well, that probably won't be good enough for video streaming, so what about an interface straight to an Android phone using the Android interface board? Would that support actual 3G speeds?"
Bill Bonney replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"The drone cell is 2.5G GPRS at a max data of 85.6kbps. Is that enough for your needs?"
McCarthy Wynkoop replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"Regarding cell towers only being by the highway, at altitude (I have friends with private planes that can attest to this) cell reception is excellent, and encompasses a good portion of the Kenai Penisula. I've decided on using Dronecell with a…"

Bill Bonney replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"At that distance are you using highly directional attenna? What's the data rate you have achieved at those distances?"
Bill Bonney replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"The originator of the post would like to achieve video at a range of upto 20kms. What would you recommend to do that? I don't think it's possible within the scope of power you can deliver from the drone? It was suggested using 3G, but that…"
Miles Smith replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"Just a note on this. Do NOT use Xbee's for telemetry. Use the 3DR Radios instead: https://store.diydrones.com/3DR_RadioTelemetry_Kit_915_Mhz_p/kt-telemetry-3dr915.htm"
Miles Smith replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"Depending on how big of a setup you have, you can always go the unconventional route.
I've spent a lot of time in my professional field setting up long distance networks like this using Ubiquiti hardware. They have hardware that claims 40km,…"

"How long range do you want? The best long range telemetry radio I know of is the RFD900. With omnis you should get between 60 and 100km with a pair of those, especially if you configure them with a low air rate (say 19200).
Beyond that, if you want…"
Tim Wilkin replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"The operating constraints are starting to lead you into the area of something like this: High bandwidth satellite modem. Alternatively, you might be able to use a UHF radio modem (could probably handle the trees, but wouldn't handle…"
Bill Bonney replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"Have you considered the fact that in remote areas 3G coverage is along highways, but not further a field. So you may have coverage on the highway, but as you get further from it the signal will drop quite rapidly. Since 3G is in the 850/1900MHz…"
McCarthy Wynkoop replied to McCarthy Wynkoop's discussion Interested in UAVs but want unconventional setup"The problem is is that I need extreme range, up to 20km with lots of trees, no good line of sight. Try a street view of Soldotna, Alaska out on the highway. Less of mounting my groundstation on a mountain, cell would appear to be the only way…"
